Tape Flux Measurement Theory and Verification
Tape flux measurement is useful for standardizing program levels on magnetic tape records, and for measuring the performance of tapes and recording and reproducing heads. A ring-core head is the most satisfactory tape-flux measuring instrument, but calibration of the flux-to-voltage sensitivity is difficult in the general practical case. By using a -symmetrical head- construction, however, the average sensitivity of front and rear gaps is accurately calculated quite easily. For practical measurements, a -high-efficiency head- has the advantage of requiring only one (not two) measurements. The flux-efficiency of the core, and the frequency- and wavelength-response factors are all calculated and experimentally verified for both the symmetrical and the high-efficiency designs. A transfer to unidirectional flux and magnetometer flux measurement gives further verification. A flux measurement accuracy of better than 3% is achieved at medium wavelengths of 0.25 to 2.0 mm.
